A solid state soft start controller system has a power supply, an electric
motor, a thyristor electrically interconnected between the power supply
and the electric motor so as to selectively allow current to pass from
the power supply to the phases of the electric motor, a laser diode
optically connected to the thyristor, and a controller connected to the
laser diode for triggering the laser diode. Separate thyristors are
connected to each phase of the polyphase electric motor. Separate laser
diodes and associated light pipes connect the laser diode to the separate
thyristors.
